| Abstract: |
Evaluation of various rice genotypes were tested in a series of trials viz., observation nursery,
initial evaluation, coordinated varietal and coordinated farmers' field trials in the spring
season of 2009 and 20 I Oto identify the suitable rice varieties for spring season. In national
spring rice observation nursery a total of 31 and 36 genotypes were tested in 2009 and 20 I 0,
respectively. Among the tested genotypes, ADRON-117, OM 5796, OM 5939, IR 72944-1-2-
2, BAGHIXIAN, OM 2008, PSBRC, IR 79538-1-1-1-1, OM 6035, PSBRC 50, IR 68305-18-
1-1, OM 2395, OM 5625, lR 72176-307-4-2-2-3, IR 7925-4-65-1-3-2, SILUGONGGO, CT
15675-7-1-4-3-1-M, OM 7938, TR 72892-77-2-2-2, OM 4900, KAWMAS and IR 18154-5-9-
2-1-3-2 were found superior with respect grain yield. Similarly, 24 genotypes tested in initial
evaluation trials of both the years, all the observed traits were found highly significant
different among genotypes in both the years except plant height, effective tillers/m2 and
number of unfilled grains/panicle in 2009. The genotypes OM 3536 (4475 kg/ha), PSBRC 28
(4332 kg/ba), lET 1771 (4557 kg/ha), WAS-57-B-B-17-3-3-1 (4167 kg/ha), OM 1490 (4475
kg/ha) were higher grain yielder in 2009 and IR 73730-33-2-32 (4050 kglha), RR-232-1-
1(3917 kglha), WAS 57-B-B-17-3-3-1(3722kg/ha), ZHON Goo-126(3666kglha), OM-1055
(3760kg/ha) produced higher grain yield in comparison to other tested genotypes in 2010. ln
coordinated varietal trials higher grain yielding genotypes were Kachorwa Dhan-4 (4120
kg/ha), IR 73730-33-2-32 (4050 kg/ha), JET 3137 (4045 kg/ha), OM 1055 (3941 kg/ha) and
OMC 96 (3938 kg/ha). In coordinated farmers' field trials the genotypes IR51656-2K, NR274,
Kachorwa Dhan 4, OMC-96 and OM I 055 performed better than the others. |
